Safety

2.1

General information on safety

The "Safety" chapter provides an overview of all important safety aspects for optimum protection of personnel as
well as safe and trouble-free operation of the equipment.
When it is placed on the market, the frequency inverter is built according to generally accepted engineering stand‐
ards and is considered to be safe to operate. It may still be a cause of danger if it is not used correctly or as
intended by suitably trained personnel.
Knowledge of the contents of the operating instructions is one of the requirements necessary to protect personnel
from hazards and to avoid malfunctions and, therefore, to operate the frequency inverter safely and reliably.
Any conversions, modifications or additions to the machine are prohibited unless approved by Demag Cranes &
Components GmbH in writing.
2.2

Safety signs on the equipment

Any pictograms, signs or labels on the frequency inverter must be obeyed and must not be removed. Pictograms,
signs or labels that are damaged or no longer legible must be replaced immediately.
2.3

Intended use

The frequency inverter may only be used as intended and in compliance with the requirements for the owner and
the following limitations as specified in these operating instructions. Any other use may result in a danger to life
and limb and/or cause damage to the frequency inverter and/or load.
● Frequency inverters are electric drive components which are intended to be incorporated into industrial equip‐
ment or machines. Frequency inverters are available to a limited extent and only intended as components for
professional use in the sense of the standard EN 61800-3.
● The frequency inverters are marked with the CE symbol and thus meet the requirements of Low Voltage Direc‐
tive 2014/35/EC and comply with standard EN 50178/DIN VDE 160.
● The owner is responsible for compliance with EMC directive 2014/30/EU.
● The requirements of CSA Standard C22.2 No. 14-95 are also fulfilled with the granting of UL approval in ac‐
cordance with UL508c.
● Refer to the rating plate and documentation for the technical data and information on connecting these units as
well as on the ambient conditions; these conditions and data must not be exceeded.
● The frequency inverter may only be installed, used, operated, maintained and removed by trained personnel
when it is in perfect working order. Personnel must meet the requirements according to  "Operating person‐
nel requirements", Page 13.
● Intended use includes compliance with the safety warnings as well as any other instructions on assembly and
disassembly, commissioning, function and operation, maintenance and fault elimination as well as compliance
with the instructions on the equipment safety devices, any possible (remaining) hazards and protection against
hazards.
● The frequency inverter must be maintained and inspected regularly and appropriately by correspondingly
trained personnel in accordance with relevant deadlines.
● National occupational health and safety regulations must be observed and followed.
No liability for inappropriate use
The manufacturer is exempt from any liability for use other than the purpose which is technically possible and ac‐
ceptable according to these operating instructions. In particular, the manufacturer assumes no liability for damage
due to inappropriate or any other prohibited use of the frequency inverter in the sense of the "Intended use" sec‐
tion.
No liability for structural modifications
The manufacturer is not liable for any unauthorised structural modifications which have not been agreed with him.
This includes incorrect connection of the frequency inverter to devices or equipment that do not belong to our
scope of delivery, or the installation or use of third-party accessories, equipment or components that are not ap‐
proved by the manufacturer.
Prohibited practices, improper use
Refer to the rating plate and documentation for the technical data and information on connecting these units;
these conditions and data must not be exceeded.
